Fixed APSW issue 412 in apsw.ext.make_virtual_module().
Added apsw.connections() to get all connections. (APSW issue 416)
sys.unraisablehook() is called correctly (APSW issue 410)
Be stricter where bool values are expected (eg VTTable.BestIndex()), only accepting int and bool. Previously you could for example supply strings and lists, which were almost certainly unintended errors.
